I think he'll be straight as long as he stays out of Brooklyn, and doesn't troll too hard. If this was LA, it might be different. But in 2020 NYC, nobody even semi famous is getting wacked over something like this. It's just to hard to get away with.
My guess is he does 1 or 2 albums, a book or movie, some interviews, and then he'll be mostly gone. He'll be like Henry Hill or Sammy Gravano, etc.... popping up every once and a while, but pretty much out of the picture.
The terms of his parole keep him on ice for about 5 years, that plus the fact that he's a snitch, mean he can never go back to what made him famous.
